If you mean recirculating ice water through the chiller, then by all means. As long as you can hook everything up to standard hose fittings (1 male, 1 female.) It's just a standard copper coil, though it's gotten a little bent up over the years. it should be able to take pump pressure, I think the fittings are swaged on.

The gruit went as planned. The starting gravity was 1.088, and it was beginning to bubble the airlock by the time I got it home. By the next day, it was fermenting very hard, and was blowing out of the blowoff tube. Yesterday I removed the blowoff tube, and put an airlock on it. As of today, the krausen is pretty much gone, but the airlock is still bubbling every 4 seconds. It smells great, and is fermenting nicely. I'm planning on letting it sit for another week before I transfer it to a secondary.

Update 2:
Transferred it. Tastes different, but awesome (thats what I expected from a brew without hops, no way it will taste the same). Nice and strong. Changed the plans a little based on the tasting.

Omitted the additional Yarrow, didn't seem to need it, still had a nice aroma.
Reduced the oak to .5 oz, don't want to over oak it.
Omitted the white oak bark, figured that the high dollar french cubes smelled and looked so good, that we didn't need anything else.

We had some at the last meeting. It has aged very well. a good beer. I would like to do one every year. Mob Barley still has the herbs we need to brew with and has offered them to the club if we want to do it again, but I guess I'm the only one who wants it to be a club tradition.
